USB to spdif adapters on Cubox-i?

Has anyone tested any of these?. It strikes me that with the internal oscillators and asyncrenous USB the better ones can provide, they should be able to draw bit perfect 24/192, from the Cubox-i ? - Hiface TWO claims to have native linux USB 2.0 drivers and should work out of the box… Someone on the Solid-Run forum tested with Cubox-i and it worked, but not sure which distro he used.
